    This is an experimental building.  This is also the only experimental building in the military division that is not located in the scientific research area, but is placed in the heavily guarded military division headquarters.  The whole building has six floors above ground and three floors underground.  ?The third to sixth floors are mechanical, electronic, chemical, and biological laboratories respectively.  The first and second floors have been opened up, with an area of ??1,600 square meters and a height of seven meters. It is equipped with various self-made assembly equipment of the military division such as automatic cranes, arc welding equipment, small electric vehicles, etc. It is a fully equipped general assembly workshop.  On the first and second underground floors, there are large, medium and small, as well as micro automatic machine tools with marble pedestals, supplemented by various advanced automated measuring instruments, capable of performing extremely high-precision CNC processing.  The three underground floors are the power distribution center of the entire experimental building. Power is distributed to the laboratory through three independent wires to ensure that there will be no power outage due to line problems.  At the same time, as a backup power source in emergencies, a set of 2,000 kilowatt heavy oil generator sets and oil reserves are also prepared to serve as backup power supply when three lines are interrupted at the same time.  At the same time, each laboratory is also equipped with a set of 600-watt large-scale uninterruptible power supply as a support before the power is suddenly interrupted and the backup engine in the basement has not been started.  The tight security and advanced equipment of the entire experimental building are unparalleled in the military division and exceed any domestic scientific research institution.  Even compared with foreign laboratories, it is not necessarily inferior, and may even be better in some parts.  The owner of this experimental building is naturally the supreme commander of the military division¡ªGuan Fei!  Xincheng¡¯s scientific research capabilities and precision manufacturing levels continue to improve, a large part of which is due to the contributions of domestic scientific research technicians and outstanding technicians. This will of course be of great benefit to accelerating the manufacturing industry in military divisions.  But at the same time, if he wanted to do some research and manufacturing in private that transcended the background of the times, it would be difficult for him to hide it from the attention of interested people.  Guan Fei doesn¡¯t really care about learning skills from military divisions in China, but he doesn¡¯t want to not have any trump cards in his hand.  In the future, he will gradually start the secret research and development of certain technologies. These technologies will be an important guarantee for the survival of the military division.  If we can keep it secret for a while longer, we can buy more time for the military division to grow.  So he carved out a small valley in the deepest part of the camp and built such an experimental building.  There are more than 6,800 soldiers and elite guard battalions protecting it. Not to mention outsiders, even Zhang Shengguo and others are not allowed to enter unless they are invited.  There are one hundred and twenty-four researchers and sixty-three outstanding technicians in the laboratory building, all of whom he has repeatedly observed and carefully selected over the years. They are either scientific research madmen who are extremely obsessed with technology, or they are loyal and reliable followers.  They usually live in the dormitory next to the experimental building. In addition to being restricted from going out, their living conditions in all aspects are much higher than those of other cadres and masses in the military subdivision.  Guan Fei¡¯s biological secondary brain personality recognition program is not omnipotent and cannot guarantee that these people are 100% loyal.  But with their precise analysis, at least in the absence of sufficient opportunities, they were able to keep secrets and would not easily leak them to the outside world.  ??At least for now.  ¡°Moreover, a person¡¯s change must be a long-term process, and there will definitely be various external manifestations. People who can perfectly hide changes in their mentality can only be well-trained espionage elites.  Even if he is 007, he will leave all kinds of clues when doing things, and it is impossible to hide them from Guan Fei's eyes.  ¡­ ¡­Zou Yongdong stood in front of a vertical CNC machining center, staring unblinkingly at the workpiece moving forward, backward, and rotating left and right under the control of the operating arm, with an obsessed expression.  He has watched this scene no less than a hundred times, but he is still deeply fascinated by it.  The great power of industry is concentrated in it.  He never imagined that he, who used to think he could only be a top soldier, would reach this level today.  Because he passed the exam, he was one of the first batch of troops to be selected to enter a technical school to learn machine tool operation. However, due to slow progress, he was thrown away by his master to learn the newly established CNC lathe.  Unexpectedly, he was on the right track. Relying on his superior memory, he quickly distinguished himself in the operation of CNC machine tools. After entering the precision machinery factory, he became the number one CNC machine tool technician in the factory.  Probably because I suffered too many setbacks in the past twenty years. No matter how ups and downs life may be, whether it is serving as a soldier, learning technology, being rejected by the master, or later becoming the respectful title of "Master Zou" or "Technician Zou", Zou Yongdong  They are all favors and humiliations, and they are still responsible for their own work, doing their own things honestly, not being proud, not complacent, not opportunistic, and not working hard to gain success.  "Compared to his senior brother Kong Lingchen, who is now an alternate deputy to the National People's Congress, he is like an unknown pebble, without a glamorous appearance, and always sticks to his duties.  When Kong Lingchen actively joined the party, he did nothing but silently operated his data.Lathes have completed the production of high-precision parts that are urgently needed in factories one after another.  As a result, Kong Lingchen tried several times but was rejected.  He, an ordinary technician who had never said a single heroic word, was interviewed many times by the factory party committee. He was repeatedly mobilized, talked about the vanguard, talked about responsibility and taking the lead, and tried every means to get him the title of party member.  title.  Before he heard a few harsh words from his senior brother, he was approached again and asked if he would like to join a secret department to contribute to the development and growth of the military division. ?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? out  ¡°After several screenings and two personal interviews by Guan Fei, the supreme commander of the military division, his name was completely removed from the list of workers at the precision machinery factory where he had worked for two years, and he came to this heavily guarded place.  The management system here is very strict and everyone can only do their own thing.  You must not ask questions that you shouldn't ask, otherwise you will be removed from the list immediately.  If you are asking for top-secret information, you may be sentenced or even shot!  Zou Yongdong didn¡¯t dare to violate discipline, and he didn¡¯t have much interest in knowing other people¡¯s affairs.  For him, it is his duty to do his job seriously and complete the tasks assigned by his superiors.  When Zou Yongdong first arrived, the laboratory building was not equipped with what it is now. CNC machine tools and other equipment were all equipment used in precision machinery factories.  The five-axis CNC machining center in front of him was all made by their own hands, one steel scrap after another, under the guidance of the commander for more than a year!  Of course, all the design drawings, tooling drawings, and parts drawings are all provided by the commander, and they just process them according to them.  Some parts that require extremely high precision can only be made by the commander himself.  During assembly, it was the commander who did the work, and they could only help out, handing over parts, tools, etc., but they couldn't be of much help.  Don¡¯t say that technicians like them can¡¯t help much, but those technicians are not.  The control circuit was designed by the commander, the components were provided by the military division, the chips were purchased from abroad, and finally even the program was entered character by character by the commander.  They just help solder a component and check whether there are any welding errors or component damage.  Speaking of which, this batch of equipment is the most top-notch and most precise processing equipment Zou Yongdong has ever seen.  For example, the alloy materials used in various precision parts are provided by military divisions. In order to meet the different physical requirements of different parts, dozens of furnaces of steel are smelted according to different formulas!  The wear resistance, impact resistance, stiffness and strength of parts made from these new materials are far superior to those before, and their service life is also several times longer than before.  For another example, in order to ensure the deviation during processing, the tools used are also specially made. The errors caused by tool wear during tool changes and long-term processing are reduced to a rare precision of 0.006 microns.  For another example, in order to ensure the errors caused by the movement of various mechanical components, a large number of optical and laser measurement equipment are used.  Although these instruments are bulky, they are really useful. Their detection accuracy is as high as one thousandth of a micron, and then through error compensation, they are precisely controlled by high-precision servo motors imported from Japan, thereby improving the positioning accuracy of the workpiece and tool.  Increased to five thousandths.  Not to mention various other modifications, even the coolant during processing is specially configured, which not only improves the processing accuracy, reduces tool and grinding tool wear, but also prevents rust and mildew, and cleans the workpiece.  , and it does not hurt the skin - although the previous coolant was effective, it was very harmful to the skin. Due to long-term contact, the cuticle on the surface of Zou Yongdong's palms was severely damaged, making him look very old.  After the military division devoted all its efforts to build it, it took more than a year to finally come up with this batch of top-notch processing equipment.  In terms of investment, even if the military division is not short of money, to be honest, it does not have the financial resources to comprehensively upgrade all factories according to this standard.  If all the investment is counted as money - although some core components can only be completed by the commander, even if you have money in the outside world, you can't buy it - just the five-axis linkage CNC center in front of you is three meters high and five meters wide.  It's worth millions of yuan, maybe even more expensive But you get what you pay for, that's true.  The processing capacity of this machining center is really amazing. Put a forged workpiece on it, and in less than an hour, an engine cylinder that is sparkling and has an extremely smooth surface is finished even if it is no longer polished!  With the complexity of this cylinder, Zou Yongdong roughly estimated that it would take at least forty hours if the previous manufacturing method was still used!    This is the power of technology!  Although Zou Yongdong has processed on this five-axis linkage CNC center hundreds of times, he puts in the same investment every time and is moved by this power.  A trace of alloy chips fell from the cylinder, and milky white coolant flowed down from above, cleaning the workpiece.  The finishing tool has completed the last process, slowly retreating and resetting under program control, and the clamped cylinder also slowly stops moving.  Ding, there is a clear sound, the red indicator light of the CNC center being processed goes out, and the green light next to it lights up, indicating that the operation has stopped and the workpiece can be removed.  The locked inner buckle also retracts automatically, and the imported explosion-proof glass door gently opens a crack.  Zou Yongdong sighed slightly.  This CNC center is easy to use. Unfortunately, because it is a five-axis linkage, it involves too many and complex parameters, making programming extremely difficult.  Moreover, the commander did not give them the specific programming method. It is said that this is just a preliminary version using imported chips. It will soon be replaced by a homemade processor in the military division, and it will still be used in a Chinese environment. In order to prevent them from having to worry about the control that is about to be eliminated.  system, so we don¡¯t teach them how to program CNC.  This also makes Zou Yongdong and the others only follow the set procedures to monitor the operation of the equipment and deal with emergencies. At other times, they just move workpieces up and down, acting as ordinary workers.  Seeing such advanced equipment but not being able to fully master it and use it freely is the biggest torture for technicians like them.  There is no other way but to hope that the military division¡¯s self-made Chinese processor can be developed as soon as possible.  "Has it been processed? How are the other parts?" Zou Yongdong was about to take out the processed cylinder when he heard a familiar voice coming from behind him. He responded reflexively, "Well, including this one,  Ten cylinder blocks have been completed. The crankshaft components and gears have also been completed, and are undergoing the final polishing process. The cylinder heads and pipes have been completed this morning and are being assembled" As he spoke, he suddenly realized  Whoever asked the question quickly and carefully placed the cylinder, turned around and said with an embarrassed smile: "Commander, I didn't know it was you" "It's okay, it's okay. When I came, I saw that you were very dedicated to your work, so I didn't bother you.  You." Guan Fei smiled. He had a very good impression of this serious young man. The deputy biological brain also ranked him among the top twenty. He was a good seedling worthy of vigorous cultivation, so he waved his hand to tell him not to be cautious.  , changing the topic aside, "Then this batch of workpieces have finally been processed. After finishing the honing and the final cleaning process, we can assemble it tomorrow." Honing is to use oilstone to finely polish the cylinder running pipe.  The accuracy is higher than the machining accuracy.  Domestic processing accuracy has not been improving, and many precision parts have been improved to aerospace level by fine grinding.  The boron nitride whetstone developed in a small amount by the military division laboratory can improve the grinding accuracy to an ultra-high precision of two thousandths of a micron, which is no less than the highest level abroad.  Guan Fei laughed with satisfaction as he watched Zou Yongdong send the cylinder to be honed on a wheelbarrow.  This smile is not only satisfied with the speed of processing and that it can be assembled and used immediately, but also a commendation for skilled workers like Zou Yongdong.  When they grow up, the future of the military division will be completely different!
